PRIME Minister David Cameron is being urged to intervene in the case of a woman facing execution in Malaysia, after she was arrested in a drugs raid.

Mum-of-two Shivaun Orton, 41, whose mum and sister live in Harlech, was arrested with her husband Abdul Harris Fadilah, 46, after police found drugs, including heroin, in the hotel the couple own in Cherating.

“I have written to the Prime Minister and the Secretary of State Jeremy Brown and to the urging they look closely at the circumstances.”

Shivaun’s mum Shirley, 73, said of her daughter’s arrest: “I’m grateful for all the interest but really I don’t know enough about what is happening out there to be able to comment at this stage.”

Shivaun's younger brother, Daniel, who lives in Leicestershire, has started internet campaigns to gather support to ensure his sister is not hanged.

More than 350 people have joined a Facebook page in support of Shivaun since her arrest in December.

He said Shivaun has pleaded not guilty to drugs trafficking and possessing cannabis, amphetamines and 225g of heroin. Malaysia's strict drug laws carry the death penalty for possessing more than 15g of heroin.

He said: “Foreign Office officials will be visiting Shivaun this week and I have sent letter from us to take to her.”

Describing his sister as a “caring, loving woman”, he added: “No matter what we believe about the facts of the case, it's a woman's life at risk and she's a person with two sons who need her.

“We'd ask the prime minister of Malaysia to show leniency.

“We respect his country and his laws, but it's my sister. We want her home.”

A Foreign Office spokesman said: “We can confirm Shivaun Orton has been charged with offences under the dangerous drugs act and a member of the High Commiszsion staff has visited her.
